Get Tangent Method

The Get Tangent method returns the tangent of an angle in radians. You specify the value in the number argument in radians. This value can be positive or negative. To convert degrees to radians, this method multiplies degrees by PI/180. The value of PI is 3.14159.

For information on how this method handles the data type, see How Some Math Methods Handle the Data Type.

Tan(number)

The following table describes the arguments that you can use with this method.

Argument	Description
number	A numeric expression that contains the number of radians in the angle whose tangent this method returns.

Example

The following example finds the height of the exterior wall of a building, given the roof pitch and the length of the building:

Sub Button_Click
   Dim bldglen, wallht
   Dim pitch
   Dim msgtext
   Const PI = 3.14159
   Const conversion = PI/180
   On Error Resume Next
   pitch = 35
   pitch = pitch * conversion
   bldglen = 150
   wallht = Tan(pitch) * (bldglen/2)
End Sub
